From: Vincent Stehlé Date: Tue, 18 Jun 2013 14:23:05 +0000 (+0200) Subject: fb: make fp_get_options name argument const X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a66e62ae56307e587e93d7ed4d83ea34c71d2eb9;p=linux-beck.git fb: make fp_get_options name argument const drm_get_connector_name now returns a const value, which causes the following compilation warning: drivers/gpu/drm/drm_fb_helper.c: In function ‘drm_fb_helper_parse_command_line’: drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of ‘fb_get_options’ discards ‘const’ qualifier from pointer target type [enabled by default] In file included from drivers/gpu/drm/drm_fb_helper.c:35:0: include/linux/fb.h:627:12: note: expected ‘char *’ but argument is of type ‘const char *’ As fb_get_options uses its name argument as read only, make it const. This fixes the aforementioned compilation warning.
